Question

我的一个客户端需要通过curl（php-curl）发送到plupload php脚本的文件（图像）。问题是文件似乎应该与块一起发送。

你能否提示我如何用php将文件发送到这个脚本？

这是接受文件的上传脚本文件。

我评论了php脚本的以下几行，其中涉及到chunking。当请求分块参数不存在时，您将看到整个文件大小写包含在默认情况下。

// $chunk is the index of the chunk being uploaded. 
// Considered as 0 if not present in the request (whole file, or fist chunk in chunking mode)
$chunk = isset($_REQUEST["chunk"]) ? intval($_REQUEST["chunk"]) : 0;

// $chunks is the number of upload chunks. 
// Considered as 0 (whole file, no chunking) if not present in the request
$chunks = isset($_REQUEST["chunks"]) ? intval($_REQUEST["chunks"]) : 0;

 // if handling the first chunk (or whole file) open temp file in create mode, else in append mode
 $out = @fopen("{$filePath}.part", $chunk == 0 ? "wb" : "ab");

// if not in chunking mode (!$chunks) or finished processing last chunk, rename the temp file to target nam
if (!$chunks || $chunk == $chunks - 1)

希望这会有所帮助

根据您的评论，当前页面应该发布文件，文件名为defaultname.txt

<html> 
  <head> 
   <title>Upload Form</title> 
   </head> 
<body> 
 <form enctype="multipart/form-data" action="/upload.php"; method="POST"> 
    <input type="text" name="name" size="20" value="defaultname.txt"/> <br /><br /> 
    <input type="file" name="file" size="20" /> <br /><br /> 
    <input type="submit" value="upload" /> 
 </form> 
</body> 
</html>

通过curl发送文件到plupload chunked
